  • You’re Not Searching the Web (How Google Search Really Works)
    Apr 14 2026

    Google Search feels like magic because it is solving an impossible problem on your behalf: you show up with a complex information need, type a couple of words, and expect a great answer almost instantly. We unpack what’s really happening in that split second, from the early days of cluttered 90s search engines to why Google’s clean interface, speed, and relevance changed everything.

    We walk through the core machinery that makes web search work: crawling (and why it has to be “polite” to websites), building and refreshing a copy of the web, and using an inverted index so results can appear in around 200 milliseconds. From there we get into ranking, including PageRank and why links became a proxy for credibility, plus the constant battle against spam and how SEO sits in a tricky grey zone between good practice and gaming the system.

    Then we zoom out to what’s changing now. Human judges still evaluate search results at industrial scale to improve quality and train machine learning systems, while query understanding rewrites and repairs your input so the ranker has a fighting chance. Finally, we tackle the shift away from the ten blue links era as AI summaries and LLMs like ChatGPT reduce clicks, introduce new trust issues, and force new monetisation choices that could reshape search again.

  • AI Is Already Better Than You Think with Ramez Naam
    Apr 7 2026

    AI did not creep in quietly, it arrived like a tidal wave. We talk with Ramez Naam, computer scientist, science fiction author, futurist, and climate tech investor, to pin down what today’s large language models really are, why they’re the fastest adopted general technology in history, and why “impressive” is not the same thing as artificial general intelligence. Along the way, we challenge the idea that AGI is right around the corner, even as these tools already outperform any single human on breadth of knowledge and rapid synthesis.

    We get practical about capability and risk: where ChatGPT, Claude, and Gemini shine, where they still fail, and why supervision and verification are the new baseline skill for knowledge workers. We also unpack why the AI model race keeps flipping leaders, why user data may not create the kind of network effects people assume, and what recursive self-improvement would need to be real rather than wishful thinking.

    Then we go straight to the biggest near-term shock: coding with AI. Vibe coding and modern developer tools are collapsing the distance between an idea and a working app, which raises hard questions about software engineering careers, junior hiring, and what “good” looks like when you are managing an army of bots. Finally, we zoom out to the energy and infrastructure behind AI, from data centres and grid bottlenecks to the case for solar-and-battery powered compute, including why Australia could be well placed.

    If you’re curious about the future of AI, AI jobs, AI reliability, data centres, and what the next ten years might realistically hold, this conversation will give you a grounded framework. Subscribe, share the episode with someone who debates AI with you, and leave a review with your most surprising takeaway.

  • How Big Tech Really Works (From the Inside)
    Mar 31 2026

    Big tech isn’t a buzzword anymore, it’s the scaffolding holding up the modern economy and, increasingly, modern politics. We sit down and map the real shape of power behind the Magnificent Seven: Apple, Microsoft, Amazon, Alphabet, Meta, NVIDIA and Tesla. We talk through what they do, why they dominate the S&P 500, and the part most people miss, where the revenue comes from versus where the profit actually lands. If you’ve ever wondered why Amazon can run on thin retail margins while AWS prints cash, or why Google Ads is still one of the greatest business models ever built, we make it plain.

    From there, we zoom out to the global dependencies that make big tech feel both impressive and fragile. Taiwan’s TSMC sits underneath much of the semiconductor supply chain, and that reality turns “chips” into geopolitics. We also touch on non-US giants like ByteDance and Samsung, then bring it back to the West Coast to ask why Seattle and the Bay Area became such powerful innovation hubs in the first place, from universities and defence roots to talent density and network effects.

    Then we get into the part everyone really wants: what it’s like inside these companies. We unpack Silicon Valley compensation and culture, including base salary, bonuses and RSUs, how vesting creates golden handcuffs, and why perks like free food and on-campus services can be both brilliant and slightly manipulative. We also talk about the uncomfortable employee vs contractor divide, and what performance cultures look like when KPIs and reviews are relentless.

    Finally, we tackle the looming disruption: AI coding tools like Claude Code, vibe coding demos, and what happens when “writing code” stops being the main job. Are we heading towards fewer engineers, better engineers, or just a different definition of software engineering altogether?
